Rethoret (1945) describes which the fire investigator should “research closely the depth of carbonization at several areas, as this can carry the investigator in receiving again to The purpose of origin”. Straeter and Crawford (1955) text discovered that “the point of deepest char during the wood is probably going to become The purpose of origin from the fire”.
